Detailed explanation-1: -On the other hand, if Earth took Mercury’s place, it would be too close to the Sun and its water would form a steam atmosphere, quickly boiling off. The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the Sun is called the habitable zone, or the Goldilocks zone.
Detailed explanation-2: -Goldilocks planet falls within a star’s habitable zone and is neither too close nor too far from a star to rule out liquid water on its surface, and thus life.
Detailed explanation-3: -Named for the “not too hot, not too cold, but just right” statement, the Goldilocks Zone (or habitable zone) represents a zone around a star that has the right conditions to allow for liquid water (between 0oC and 100oC).
Detailed explanation-4: -Planets or moons located in the Goldilocks zone are at the right distance from their star so that they’re not too hot and not too cold-just like Baby Bear’s porridge in the fairy tale. Their overall temperature is just right for the formation of liquid water, a landmark of life.
